In the 'L053 DS, DS10152 Rev 9 , pin PB5 is marked as TIM22_CH2 both in Table 15. STM32L053x6/8 pin definitions and Table 17. Alternate function port B . However, this is an exceptional pin which can be remapped to TIM3_CH2. The DS in both tables sho...
Hi , I am trying to flash my code of GPIO toggle into the STM32H745 Disco board,but it is giving the error .While building the project I have seen an error "GPIO_CM4\GPIO_CM4.sct(7): error: L6235E: More than one section matches selector - cannot all...
Posted on July 03, 2016 at 10:49Hello,I generated the code using the STM32CubeMx.I'm trying to I2C communication between STM32F4(master) and IC(slave, 7bit address).I tested to two functions for I2C communication.HAL_I2C_Mem_Write is OK, but HAL_I2C...
The question pertains to maximum rise time specification for STM32L151CC OSC32_IN when Low-speed external user clock is generated from an external source. This specification, according to the datasheet, is 10 nano seconds. This seems unreasonably fas...
Hello,In the STM32H753AI datasheet, there are footprint guidelines for all the packages, except for the UFBGA169 (see attached image).Has anyone built a board with this package? Where did you find any info on this type of package?Is there a database ...
I'm creating an I2C library for PCA8596 to control servos using STM32F4 Discovery as master. I already checked the PCA using arduino, and it worked. It also compiled well and can be uploaded.The problem is the SCL and SDA from the stm didn't generate...
ST,Please update AN4861 for 'H7Please link to AN4861 from the 'H7 product folder webpagesPlease fix links to AN4861 on forum - those given by Amel and Imen are usually broken, you can find them by searching for DM00287603Thanks,JW
Hello everyone, I want to work on STM32 series of controller which supports 480MHZ or above clock rate and Auto grade temperature range(I.e Grade0: -40degc to 150degc (or) Grade1:-40degc to 125degc).We found STM32H7 series which supports our applica...
I am witnessing interrupts on EXTI9_5 line which have absolutely no electrical stimulus. I'm seeing this behavior consistently on multiple chips so this isn't a one-off.The GPIO in question (ONE_WIRE_PIN) is PA8.GPIO initialization here:mIRQConfig.Pi...
